Hi all. I bought the Anker 20000mah battery for my XT10g, StarSeek wifi, and equatorial mount. It works great on all, but the included multivolt cable kept coming loose in the telescope power socket! It is a tiny bit infuriating to just finish a polar or 2/3 star alignment, only to loose power and have to do it all over again!

I started digging, and it turns out that the Anker multivolt cable has a "type N" adapter (2.5mm inner diameter) on the outgoing end. Both of my telescopes and the StarSeek have "type M" connectors (2.1mm inner diameter). The bigger pin opening of the included cable makes the connection to the telescope and StarSeek flaky.

So... I took a ride to RadioShack. They have an plug system called Enercell Adaptaplug. I made a cable with the correct connectors using the Enercell 6' female-to-female socket cable, an Enercell type M connector (for the telescope), and an Enercell type B connector (for the Anker multivolt port). It works great! No more flaky connection! Total cost was about $25. Pricey for what it is, but well worth it for a solid power connection!
